She may like a traditional vape like the ones with big pyrex rebuildable tank like the nicotine addicts use but more likely the discreet setup I use she'll like.Which brings up another question... Which refillable carts ARE the good ones? Like, if I wanted to make my own vapeable THC liquid. I personally prefer bong hits, but my sister has hinted (not so subtly) that she'd like me to make some carts for her to use when she's out and about. I'm very familiar with RTAs, RDTAs, etc., but not the refillable self contained cartridges.
